STOPPER FOR BOTTLES, 86C.

PECIFICATON forming part of Letters Patent No. 696,571, dated April 1, 1902.. Application led July 9, 1898. Serial No. 685,518. (No model.)

To @ZZ 'Lz/72.077@ it may concern:

Be it known that I, GUSTAVE KOCH, a subject of the German Emperor, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Stoppers for Bottles and other Receptacles, of which the following is a specification.

The invention relates to improvements in Stoppers for bottlesand other receptacles; and it consists in the novel features and combinations hereinafter described, and particularly pointed out in the claims.

The invention comprises a bottle or other receptacle having an annular groove encircling its mouth and a stopper which will close said mouth and be of such construction that an annular depending compressible flange thereon will enter the aforesaid annular groove and firmly engage the walls of the same, whereby said stopper becomes locked upon the upper end of the bottle or other receptacle and effectually closes the same. The? said annular groove is formed in a thickened section integral with the bottle or receptacle and is disposed exteriorly to the usual throat of the bottle or receptacle, and the said thickenedsection is thus of unyielding material and furnishes rigid walls for said groove.

In this application I illustrate the invention in several modiiied forms, which will be described hereinafter and are illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section of a bottle neck and stopper constructed in accordance with and embodying the invention, the dish-shaped end of that portion of the stopper which enters said neck being shown in its initial shape. Fig. 2 is a like view of same, showing the dish-shaped end of the stopper as having been flattened to thereby the more securely lock the stopper in position. Fig. 3 is a like view of a modified form of a part of the invention, the iiat top of the stopper being shown in its initial shape. Fig. 4 is a like view of same, showing the flat top of the stopper as having been depressed` to more firmly bind the stopper against the inner edges of the mouth of the bottle. Fig. 5 is a like View of a further modified stopper and bottle embracing some of the features of the invention. Fig. G is a like view of a stopper and bottle of slightly-modilied form and embracing some of the features of the invention. Fig. 7 is a like View of a stopper 55 and bottle of modified form and embracing some of the features of the invention. Fig.

8 is a top View of a bottle with the stopper or cap removed. Fig. 9 is a top plan view of the stopper or cap shown in Fig. 1. Fig. l0 6o is a central vertical section showing a further modified form of stopper. Fig. 11 is a like view of same after the annular bead on the depending flange has been iiattened to lock the stopper or cap and bottle together. Fig. 12 is a like view showing a further modiiied construction adapted more particularly for milk bottles or jars, the cap in this ligure consisting of a flat circular disk. Fig. 13 is a like View ofrsame, showing the application of the disk illustrated in Fig. 12 to the annular groove in the bottle-neck; and Fig. 14 is a side elevation, partly in the central vertical section, of the tool by which the Stoppers or caps hereinbefore referred to may be applied to the bottle.

In the drawings, A designates the bottle, and B the cap or stopper therefor. The bottle A is provided with the thickened section C around its upper end, and within this thickened portion C is formed the annular vertical groove D, encircling the mouth of the bottle. The section C is integralwith the material of the bottle -neck and furnishes rigid or unyielding walls for the said vertical groove D.

The stopper B shown in Figs. 1 and 2 is formed with the central depending plug portion E and with the depending annular flange F, the latter being formed by bending downward and then upward the portions of the metal which extend laterally from the annular edges of the plug portion E. The iange F is thus formed of two layers of the metal of the stopper, and in their initial condition 95 lthese two layers of metal are separated from one another by a space and constitute the hollow iiange F, whose diameter is greater than the diameter of the annular groove D, into which during the application of the stopper to the bottle the said flange is driven. The driving of thc flange F into the annular ICO groove D results in said flange having its sides compressed or contracted and conformed to and brought into locking and sealing contact with the walls of the said groove D, whereby the stopper or cap is firmly held upon the bottle. In some instances it is desirable that the stopper or cap B be provided with the depending plug portion E, having the dish-shaped bottom G, and in other instances the dishshaped bottom G may be omitted, and in other instances the depending plug portion E may be omitted. When the stopper is to be used for sealing highly effervescent or gaseous liquids, it will be found desirable to employ the depending plug E, since this plug will form an effectual sealing medium and will coperate with the flange F in locking the stopper in the bottle so firmly that it will retain its position under all usual and under many unusual conditions.

In the employment of the stopper shown in Fig. 1 the plug portion E is driven into the neck of the bottle and the hollow troughshaped flange F is simultaneously forced into the annular groove D, and the result of this operation is to contract and conform the sides of the plug E to the walls of the bottle-neck and force said sides into intimate binding and sealing contact with said walls and also to force said flange F into the narrower groove D, and thereby contract or compress said flange, so that it will firmly bind against the walls of said groove and be made to conform tosaid walls and be brought into intimate binding contact therewith. The stopper shown in Fig. 1 is thus locked upon the bottle by the operation of the flange F in conjunction with the groove D and also by the contraction and compression of the plug E against the inner walls of the neck of the bottle. In its initial condition the diameter of the plug E is somewhat greater than the diameter of the bottle-neck, and hence when said plug is forced into said neck its sides are compressed and conformed to said neck and broughtinto sealing-contact throughout their length therewith. The stopper may then be additionally locked in position by the flattening-of the dish-shaped bottom G of said stopper, whereby said bottom G is caused to form a disk wedge between the walls of the plug E, as shown in Fig. 2, and hold the sides of the plug firmly against the walls of the bottleneck.

The stopper shown in Figs. 1 and 2 is entirely useful and effectual for sealing bottles containing highly charged or effervescent liquids. For other liquids only lightly charged with gas or containing no gas whatever all of the locking means shown in Figs. 1 and 2 are not necessary, and hence in the other figures of the drawings I illustrate various stoppers, showing some of the features of the invention, but not possessing all of; the locking and sealing means illustrated in Figs. I and 2.

In Fig. 3 thestoppcr is shown in the form of a disk having a depending annular troughshaped or open flange F to enter the annular groove D in the manner explained above with reference to the stopper shown in Fig. 1. The stopper shown in Fig. 3 after being applied may have its central portions driven downward in the manner indicated in Fig. i in order that the metal top may be caused to closely impinge the upper inner edges of the bottle-neck, and thereby aid the flange F in sealing the bottle.

The stopper shown in Fig. 5 in its initial form corresponds with the stopper shown in Fig. 3 and depends for its locking and sealing wholly upon the driving of the flange F into the groove D.

The stopper illustrated in Fig. G corresponds substantially with the stopper shown in Fig. 5; but the flange F is formed by folding the metal downward and then inward and upward, as shown, instead of downward and then outward and upward, as in Fig. 5.

The stopper shown in Fig. 7 corresponds substantially with the Stoppers shown in Figs. 3, 4r, and 5, with the exception that the central portion of the stopper instead of being close to the upper edges of the bottle- 'neck is raised above said edges.

The stopper shown in Figs. 10 and. 11 has its depending flange F in the form of an annular bead, as shown in Fig. 10, which bead, when the stopper or cap is applied to the bottle, will be flattened, as indicated in Fig. 11, whereby the opposite portions of said bead are caused to press laterally against the IOO walls of the groove D and lock the stopper or cap upon the bottle.

Fig. 12 illustrates one method of applying to the bottle the cap or stopper and the formation of the depending flange F at one operation. In Fig. 12 the cap or stopper is shown as consisting in its initial form of a flat disk of metal, paper, or other suitable material, and Fig. 13 illustrates the same disk as having had its outer portions depressed into the annular groove D to form the depending trough-like flange F,binding against the'walls of the groove D.

In Fig. 14 is illustrated a convenient tool by which the stoppers or caps may be applied to the bottle. This tool is lettered M and preferably is provided with the two annular plungers N O, the former being adapted to enter the annular groove D of the bottle and the latter being adapted to encompass the outer edges of the bottle and operate as a guide for directing the plunger N into the annular groove D. In the event that any of the edges of the Stoppers or caps shown in Figs. 1 to 5, inclusive, should be unduly wide, and thus possibly extend slightly over the outer edges of the neck of the bottle, the annular plunger O of the toolM will operate to turn said edges downward on the edges of the bottle-neck. The annular plunger N of the tool M is used for depressing or flattening the bead formation of the flange F.

IIO

(Shown in Fig. 10.) If desired, the annular plunger portion O of the toolM maybe omitted, since the annular plunger portion N of said tool may be relied upon to effect the proper sealing of the iiange F within the groove l).

All of the forms of Stoppers or caps shown in the drawings have the annular depending two-part flange F, to be locked within the annular groove D of the bottle, and, as above indicated, this flange F is so proportioned to the diameter of said groove that when therein its sides will enter into intimate binding contact therewith and lock the stopper or cap onV the bottle.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Thebottleorreceptaclehavingthethickened section C ot' unyielding `material surrounding its throat-passage and being exterior to said passage so as to leave the latter substantially unobstructed, said section having the vertically-disposed annular groove opening upwardly in its upper edges and disposed outwardly beyond the side walls of' said throat-passage, combined with the stopper or cap initially having the two-part annular depending flange adapted to enter and firmly bind against the walls of said groove, the initial diameter of said flange `being greater than thev diameter of said groove, whereby said flange upon being driven into said groove and between the unyieldingfwalls thereof becomes contracted and conformed to said walls and enters into sealing contact therewith; substantially as set forth.
